WebKit1 apps crash in ___ZN7WebCore16DiskCacheMonitorC2ERKNS_15ResourceRequestENS_9SessionIDEPK20_CFCachedURLResponse_block_invoke1 on the main thread in iOS.

This is because ___ZN7WebCore16DiskCacheMonitorC2ERKNS_15ResourceRequestENS_9SessionIDEPK20_CFCachedURLResponse_block_invoke1 is being run on the main thread, creating a race condition where the DiskCacheMonitor object can be deleted after the CFCachedURLResponseCallBackBlock grabs its pointer to use on the WebThread.
